Hello, I started using sony vegas recently and I have already found many troubles. I can't import .mkv files and so I started a research in the web to convert them in other formats. The result is that a lot of converters didn't see the .mkv files and the ones that can convert them, like avidemux and xilisoft hd video converter, don't display the subtitles of every .mkv file. I think the most important problem is with the configuration of hi10p .mkv files. How can I use that kind of files in vegas if I dunno how to convert them without losing the subtitles (and the rate quality/weight)?Thanks a lot!!! (hoping in an answer by mirkosp...)

Ugh, when I try to import the fake file .avi created thanks to Pismo File Mount and AviSynth Virtual File System it says to me that an error occurred while opening a codec... Even if the other files .avi that I have don't give me any problem if I try to open them... Where is the problem?

My cousin uses this to convert Mkv to Mp4. The resulted MP4 should work with Sony Vegas.Dont use fake avis, save yourself the frustration.

I tried this program and can confirm it works. When you import .mkv files or any video file, it disables subtitles by default but u can change it. MP4 output settings are fine as is. Quality loss from conversion is minimal. Unless the original source has alot of noise.

As for Codec problems. Not sure what the cool cats use but just get cccp and quicktime if u dont already.

it doesn't work... With Free Video Converter I obtain a video where I can see only a full screen green color and the subtitles...I think it's easier to solve the problem with avisynth... When I mout the .avs file in the folder there is also a file named error.log with this text:Video stream :- Duration: 34044 frames, 00:23:39.918 ColorSpace: YV12 Width:1280 pixels, Height: 720 pixels.
